well its good to know that few other guys are getting their cars running but i have decided that im going through the engine wiring harness wire by wire due to the fact that i know that i have all the grounds hooked up and that i have found some wires that are not in the wiring diagram and i have no idea wut they go to... so instead of guess im going to go through it all so i know wut wire is wut and i that i can remove anything that doesnt need to be in there engine compartment. it may take a while for me to get this down i only have an hour or two a day to work on it. ill keep every one updated on the status of it and when i get it running

so i finally got started on the wiring and holy crap wut the hell did i get myself into hahaha i think i found why no spark... no knock sensor wires or anything

anyother question i got into the ecu and the is the hks fuel cut defender on it. would that cause it to have no spark... i plan on removing it within the next to couple of days but i will be very tight on time due to college and work

FCD is VERY old tech and was a piece of crap and all 'round bad idea even when it was new. Pull it... It shouldn't cause a spark issue (other than causing the spark advance to be a mile off), if it were seriously damaged; It modifies the air flow signal... I don't think it even reads the IGt.

well i am going to remove it tonight... the harness is pretty hacked up so i pulled it out and im going through the whole thing and going to clean it up and tape it up right ill post pics later tonight or this weekend

well i finally got the harness down and back into the car. got everything hooked up. turned out i was missing one ground that was going to the starter and back feeding power to ecu and the knock sensor was missing as well. The car is no running can some wut drivable. needs a few kinks worked out of it. like the fuel tank and limnes need flushed out(two year old gas) need to get the air out of the cooling and power steering systems. need to install my aftermarket IC and piping along witht the intake. then the interior will go back together and it will go get some exhaust... Im thinking just three inch staight pipe, what do you guys suggest?
